CORNER FOR CORNER BEADS.

Application filed June 29, 1925. Serial No. 40,381.

This invention relates to improvements in corner for corner-beads, andmore especially to such a corner adapted for use in connection withmetallic corner-beads.

By the use of my invention it is possible to form the corner betweenadjacent strips of corner-bead accurately and quickly without requiringlaborious fitting, adjusting or cutting of metal. B the use of myinvention also, for exampfe, the right angle corners formed by thecorner-beads around a window casing may be quickly and ac curately made.

My improved device is cheap to make and is neat and durable.

Other features and advantages of my invention will appear more fully asI proceed with my specification.

In that form of device embodying the features of m invention, shown inthe accompanying di'awings, Figure 1 is a View in front elevation of myimproved corner for corner-beads, Fig. 2 is a View taken as indicated bythe line 2 of .Fig. 1, Fig. 3 is a View in side elevation of the cornerpiece itself, and Fig. 4 is a bottom view of the same.

As shown in the drawings, the corner-bead is made of a single strip ofsheet metal curved longitudinally along its length at the center to forma bead proper 10 which thus presents a rounded transverse outer surfacehaving elongated straight edges 11, llto provide the ground or gage towhich the plasterer may finish his Work and further to provide means forstraightening the plastered structure at the corners.

At the edges 11, the metal is bent back as indicated at 12 to partiallyoverlap and lie parallel with the side margins Oil/11B bead portion 10.The portions 12 are preferably spaced from the side margins of theportion 10 a distance equal substantially to the thickness of the metal.The metal from the inner edges of the portions 12 is bent away from thebead portion 10, the two sides being substantially parallel for a shortdistance, to form the narrowed throat 13. From the inner end of thethroat, the metal is bent outwardly to form the two side wings 14, 14,which lie substantially at right angles to each other and serve toattach the head to the structure to be plastered. These wings areprovided with the holes 15, l'adapted to receive the nails 16 which maynail the corner-bead to the structure to be plastered. The wings arealso provided with the usual perforations 17 having the flanges 18 whichserve as keys for the plaster.

The corner piece itselfis shown in Figs. 3 and 4. This is preferablymade out of pressed steel and it will be seen that this corner piece incross-secti0n is substantially the same as the head portion proper ofthe corner-bead. The corner piece itself is indicated in general by 19.This piece comprises the corner portion proper indicated by 20 whichforms a right angle for the corner-bead proper as shown. The portion 20is provided at each end with an ear or lug 21 which is also curvedtransversely to conform to the curvature of the head 10. The lug or ear21 of the corner piece is adapted to fit into the space between the beadportion 10 and the bent-back portions 12. The corner piece 19 isprovided with a shoulder or oflset 22 where the ear 21 joins the cornerportion 20. This oifset or shoulder 22 is substantially the thickness ofthe metal and is adapted to butt against the end of the bead portion 10of the corner-bead and form a continuation thereof. (See Fig. 1.)

The corner piece 19 is preferably stifi' and rigid so that when the earsor lugs 21, 21 are in place in the ends of the cornerbeads, a stifi andrigid corner connection for the two corner-beads will be made. The ear21 is adapted to fit snugly in the end of the corner-bead piece. It willbe seen that by the use of my invention, a corner for corner-beads maybe accurately and quickly formed without requiring any laborious cuttingor fitting. If it attempted to make a corner between the two beadswithout the use of. such a corner iece it is necessary to do veryaccurate diagonal cutting and fitting of the two ends of thecorner-beads in order to make the mitered corner. By the use of myinvention, all such work is done away with.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invenloo tion as broadly as possible in vi'w of the priorart.

What I claim as new, and desire to secure by Letters Patent, is:

1. A corner-bead structure comprising; a corner-bead formed from astripof metal bent longitudinally to provide a bead portion proper, gprtionsof said metal being bent backwar y upon itself at the edges of said beadportion proper, thence inwardly substantially parallel to form anarrowed throat and thence away from each other substantially at rightangles to form wings for attachment to a structure to be plastered; anda corner piece having a corner portion forming a right angle and adaptedto form a continuation of and right angled connection between the twobead portions proper of two corner-beads lying at right angles to eachother, said corner piece being provided at each end with an ear adaptedto be inserted into the end of one of the corner-beads in the spacebetween the head portion proper and the portions of the metal bentbackwardly upon itself at the edges of said bead portion.

2. A corner-bead structure comprising; a corner-bead formed from a stripof metal bent longitudinally to provide a bead portion proper, ortions.of said metal being bent backwar ly upon itself at the edges of saidbead portion proper, thence inwardly substantially parallel to form anarrowed throat and thence away from each other substantially at rightangles to form wings for attachment to a structure to be plastered; anda corner piece having a corner portion forming a right angle and adaptedto form a continuation of and right an led connection between the twobead portions proper of two corner-beads lying at right ang es to eachother, said corner piece bead between the ing provided at each end withan ear adapted to be inserted into the end of one of the corner-beads inthe space between the bead portion proper and the. portions of the metalbent backwardly upon itself at the edges of said head portion, said earadapted to be held snugly in said -cornercorner-bead portion proper andthe backwardly bent portions of metal at its edges.

3. A corner-bead structure comprising, a corner-bead formed from a stripof metal bent longitudinally to provide a bead portion proper, portionsof said metal being bent backwardly upon itself at the edges of saidbead portion proper, thence inwardly substantially parallel to form anarrowed throat and thence away from each other substantially at rightangles to form wings for attachment to a structure to be plas tered; anda corner piece having a corner portion forming a right angle and adaptedto form a continuation of and ri ht angled connection between the twobea portions proper .of two corner-beads lying at ri ht angles to eachother, said corner piece emg rovided at each end with an ear adapted tobe inserted into the end of one of the corner-beads in the space betweenthe bead portion proper and the portions of themetal bent backwardlyupon itself at the edges of said bead portion, said corner piece beingprovided with a shoulder or ofi'setat the juncture between the ear andthe. corner portion, whereby the outer surface of said corner portionwill lie flush with the outer surface of the head portion proper of thecorner-bead.

In testimony whereof I have hereunto set my hand this 26th day of June,1925.

CHARLES H. RICHARDS.
